Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.

24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...

11M VW diesels affected, Porsche and Audi under investigation

Volkswagen's diesel scandal is growing exponentially larger. In a new statement, the company admits that 11 million vehicles worldwide might be equipped with software capable of evading emissions testing. In addition, the Environmental Protection Agency is beginning an investigation into the 3.0-liter V6 in Audi models and the Porsche Cayenne in the US, according to The Detroit News. The automaker claims that from its investigation so far, the "relevant engine management software is also installed in other Volkswagen Group vehicles with diesel engines." However, the company finds that the "noticeable deviation" in test results and real-world numbers only relates to the Type EA 189 powerplant. That still leaves 11 million vehicles potentially skirting emissions rules, though. Governments around the world have started taking a closer look into the company, too. In the US, the EPA has begun testing VW's V6 diesel because "they were certified well before we knew what we know now," Christopher Grundler, director of the EPA's Office of Transportation and Air Quality, said to The Detroit News. The agency has started checking diesels from other automakers to make sure they're meeting the rules, as well. Germany, the European Union, and South Korea have instituted similar investigations. In response, VW is setting aside 6.5 billion euros ($7.25 billion at current rates) to cover servicing all of these diesels. The company admits that the figure might have to be adjusted depending on what happens next. The money is being deducted from its third-quarter earnings.

New vehicles from the Volkswagen Group with EU 6 diesel engines currently available in the European Union comply with legal requirements and environmental standards. The software in question does not affect handling, consumption or emissions. This gives clarity to customers and dealers. Further internal investigations conducted to date have established that the relevant engine management software is also installed in other Volkswagen Group vehicles with diesel engines. For the majority of these engines the software does not have any effect. Discrepancies relate to vehicles with Type EA 189 engines, involving some eleven million vehicles worldwide.
